Currently it is a common practice to perform a 2D MT inversion modelling of MT data measured along a profile for interpretation purpose. For that, geoelectric strike angle information is essential. Geoelectric strike angle can be determined by rotational analysis of the MT impedance tensor. In this paper we compare geoelectrical strike angle from both Swift method and polar diagram analysis by plotting the results as rose diagrams. The results from rotational analysis include a 90o ambiguity in the strutural direction. Along with information from the regional geology to resolve the ambiguity, the profile for MT 2D modelling can be more appropriately selected. We used MT data from a geothermal prospect to illustrate our exercise. Both Swift and polar diagram method show a satisfactory results in determining geoelectric strike that matches a great structure lying under the research location.<p align="justify"> text
